British North Greenland expedition

Simpson made a preparatory exploration in 1951. A Short Sunderland flying boat landed in Seal Lake and from there Simpson walked across Storstrommen to Queen Louise Land. There he found an ice-free glacial lake that would be a suitable place for landing and he named it Britannia Lake (Britannia Sø) after the future expedition. The exploration team stayed three weeks in the area, following which the Sunderland returned to bring the party back to Britain. In July 1952 the expedition sailed from Deptford aboard the former Norwegian sealer Tottan, while another cargo ship, loaded with four Weasel tracked vehicles, sailed from Hull. The expedition team consisted of 25 men; fifteen from the armed services and the merchant navy, nine civilian scientists, and a Danish army officer. After collecting sledge dogs in south-west Greenland, the two ships sailed to Young Sund in the north-east coast. From there RAF Sunderland flying-boats airlifted the expedition to Britannia Lake in Queen Louise Land and set up the main base camp of the expedition. Commander Simpson then led a party on dog sleds to establish the North Ice station about to the west. The Weasels were landed on the coast and drove the 100 miles inland as far as the base camp. Once the party arrived at the site of North Ice, their stores and equipment, more than 86 tons of it, were air-dropped from two RAF Handley Page Hastings transport aircraft, flying from Thule. During the supply operation, on 16 September 1952, Hastings No. WD492 of 47 Squadron, having already made a series of parachute drops, was making the second in series of free fall drops at an altitude of only , when it was caught in a white-out, and made a forced belly landing. Three members of the crew were injured, and sheltered in the intact fuselage of the aircraft until air-lifted out by a Grumman HU-16 Albatross of the United States Air Force. The rest of the crew were recovered two days later by a rocket assisted USAF Douglas C-47. In early 1953 glaciological studies began, while seismic and gravimetric teams worked between North Ice and Britannia Sø. Observations were continued throughout the second winter, and in 1954 a party traversed the ice cap from North Ice to Thule. Attempts to measure the thickness of the ice sheet by seismic soundings failed, but markers placed on the ice, enabled information about the movement of the ice sheet and the accumulation of snow to be gathered. At North Ice ice cores to a depth of were recovered. The expedition suffered its only fatality in 1953, when Captain H. A. Jensen of the Danish Army, a qualified surveyor, fell to his death on a steep snow slope. while Commander Simpson was also presented with the Patron's Medal from the Royal Geographical Society in 1955, and was made a Commander of the Order of the British Empire (CBE) on 2 January 1956. In the 1980s the abandoned huts of the expedition field camp were destroyed by a surge of the Britannia Glacier. ==Temperatures==
